Carrier-based aircraft landing guide 3D display method

Abstract

The invention provides a carrier-based aircraft landing guide 3D display method. According to the method, two cameras are arranged at symmetrical positions on the two sides of a runway; internal and external parameters of the camera are calibrated, the internal and external parameters of the camera on a ship body coordinate system are calibrated through a three-dimensional control point method within the time period when the ship body is relatively stable, the internal parameters comprise the focal length, the principal point and the aberration coefficient of the camera, and the external parameters comprise the optical center position and the optical axis direction of the camera; then deck deformation is corrected, shipboard aircraft distance information is obtained, the position of an ideal glide path in the image is calculated according to internal and external parameters of a camera and the shipboard aircraft distance information, and a cross wire is overlaid; and finally, corresponding areas in the images obtained by the two cameras are intercepted and sent to a 3D display to be displayed. According to the invention, the problem that the camera is frequently rolled by a shipboard aircraft or is easily illustrated when being arranged on one side in the existing arrangement mode can be avoided, and the deformation of the mounting position can be corrected by itself; and distance information of the shipboard aircraft can be obtained by itself.

Description

technical field [0001] The present invention relates to a carrier-based aircraft landing guidance method. Specifically, the video images of the carrier-based aircraft landing process obtained by the ship-based guidance camera are displayed in 3D form by using technologies such as image processing, camera measurement, and 3D display, to assist the carrier-based aircraft to land. The Ship Officer (LSO) completes the landing guidance. Background technique [0002] Carrier-based aircraft generally adopt isometric glide method to land on the ship. If a camera is placed at the ideal landing point on the centerline of the runway to shoot the landing process of the carrier-based aircraft, then if the carrier-based aircraft has been flying along the ideal glide path, it will always maintain a fixed position on the camera image. Providing this video image to LSO can provide LSO with intuitive information that the landing process of the carrier-based aircraft deviates from the ideal g...
